ABSTRACT
The classical views of organization either ignore the individual or they make oversimplified assumptions about him. A result of this oversight is the breach between theory and practice in organizations, between the way organizations should work and the way they do work. For instance, informal organization (which stems in part from the personal needs and interpersonal relationships of members) is not accounted for in the formal plan. The Hawthorne research scientifically documented this important human aspect of organization and made it patently clear that psychological or social psychological principles of behavior were at work in the test room. The research also showed that organization theory would somehow have to take these principles into account. Let us look briefly at some of the psychological and social psychological principles which are relevant to the adjustments of members and to their performance in the organization.
